Fourteen modifiable risk factors are behind nearly half of all dementia cases worldwide, a report claims, but genetics and old age are the main causes of the condition

An artificial intelligence method to detect biomarkers in tumor biopsies promises to cut weeks and thousands of dollars from cancer detection, extending the benefits of precision oncology to underserved and under-resourced patients.

An international research team has succeeded in developing a new version of RNA building blocks with higher chemical reactivity and photosensitivity. This can significantly reduce the production time of RNA chips used in biotechnological and medical research. The chemical synthesis of these chips is now twice as fast and seven times more efficient.

An artificial intelligence program created explanations of heart test results that were in most cases accurate, relevant, and easy to understand by patients.

Calculations show that nerve fibres in the brain could emit pairs of entangled particles, and this quantum phenomenon might explain how different parts of the brain work together

New research led proposes a plan to safeguard Earth's imperiled biodiversity by cryogenically preserving biological material on the moon. The moon's permanently shadowed craters are cold enough for cryogenic preservation without the need for electricity or liquid nitrogen.

Significant strides in addressing the issue of AI 'hallucinations' and improving the reliability of anomaly detection algorithms.

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar astrophysics and helps us understand the activity of the Sun, its spot structures and eruptions.

In a hopeful sign for demand for more safe, effective antibiotics for humans, researchers have leveraged artificial intelligence to develop a new drug that already is showing promise in animal trials.

Clean energy investments offer potential stability and growth, especially during volatile market conditions. A recent study explored the relationship between clean energy markets and global stock markets. Significant spillovers were observed from major indices like the SP500 to markets such as Japan's Nikkei225 and Global Clean Energy Index. These interactions suggest opportunities for optimizing investment portfolios and leveraging clean energy assets as hedging tools in volatile market environments.

Neurotransmitter levels in the brain can indicate brain health and neurodegenerative diseases like Alzheimer's. However, the protective blood-brain barrier (BBB) makes delivering fluorescent sensors that can detect these small molecules to the brain difficult. Now, researchers demonstrate a way of packaging these sensors for easy passage across the BBB in mice, allowing for improved brain imaging. With further development, the technology could help advance Alzheimer's disease diagnosis and treatment.

A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.

Physicists have experimentally demonstrates a novel physical effect that was predicted 45 years ago. The effect will result in a new chemical analysis technique, to simultaneously identify molecular bonds and their 3D arrangement in space. This new technique will find applications in pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.

Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal kingdom and setting the stage for possible future treatments for muscular disorders.

It is nearly time for one of astronomy's top annual sights – the Perseid meteor shower. This year is a bit special, says Abigail Beall

An ordinary-looking valley has a secret – each of its neighbours is 20 years removed in time. Scott Alexander Howard's debut is heartfelt and deeply enjoyable, says Emily H. Wilson

Neal Haddaway's photographs show how flesh-footed shearwater chicks on a beautiful island in the Tasman Sea are in danger from mounting marine plastic pollution

The graft involved in trying to bring the peregrine falcon, Hawaiian crow and California condor back from the brink in the US makes for compelling reading in Feather Trails by Sophie Osborn
